Abstract
The invention provides bio-enzyme and rare earth type jute fiber oil and a production method thereof. In the method, hydrogenated refined 150SN base oil and tea oil are adopted as an oiliness additive and an assistant; proper bio-oil and bio-enzyme technology is introduced; and new compound technology is adopted, and superfine microemulsion decoloration and degradation are coordinated. The bio-enzyme and rare earth jute fiber oil comprises the following raw materials: hydrogenated refined 150SN base oil, refined tea oil, solution of ionic surfactant, a non-ionic surfactant, bio-enzyme, and rare earth elements. The bio-enzyme and rare earth type jute fiber oil can soften the fiber, so that long and hard fiber of the jute fiber is bulked and refined, desquamation and end breakage rate are reduced, and the fiber hardly fuzzes and falls off. The sisal fiber treated by the product has the yarn diameter of less than or equal to 0.2mm and has the brute force of spun yarn of 346.5. Therefore, the friction coefficient between the fiber and machinery can be reduced effectively, and the jute fiber has higher abrasion resistance and hygroscopic property and is hardly ruptured in the spinning process so as to achieve the effects of reducing the end breakage rate and improving the finished product rate.
Description
Technical field
The present invention relates to a kind of sisal hemp and use fiber oil, make sisal fiber reach softening purpose, make long and hard expanded, the refinement of fiber deliquescing of flax fibre, reduce exfoliation, end breakage rate, make it a kind of jute fiber oil and the production method thereof that are difficult for fluffing, come off.
Background technology
At present, be used in meticulous petrochemical technology in the world in the sisal hemp field of textiles, integral level is higher, mainly is softening, expanded, reformation treatment technology level height to sisal fiber.Therefore can produce the sisal hemp textiles of high added value, and these high value-added products have high strength, corrosion-resistant, moisture absorption rapid heat dissipation, health, usability is good, comfortable and easy to wear, ventilative, smooth, elongation is little, advantages such as physical stability is good are enjoyed very high reputation in the international market.Continuous expansion along with market, people pursue modernization life back to nature, green environmental protection, the fabric that some sisal fibers and other fiber interweaving are formed also arises at the historic moment, as sisal hemp and polyester, sisal hemp and viscose glue and interweaving products such as sisal hemp and hair, win liking of people with its unique style.External sisal hemp textile product class is higher, and plentiful abundant, the third dimension of sisal hemp textiles cloth cover is strong, rich color, soft, good permeability.Nowadays flax fibre has been widely used in every field, and numb proportion is from 5%-100%, and product has reached variation, becomed privileged.The effect of linen fabrics clothes is not only and is hidden body, resisting cold, also plays the effect of beautify life.According to relevant expert's statistics, what be made into clothes in world's linen total output accounts for 55%.At present, the whole nation has more than 60 families of all kinds of sisal hemp source mill of certain scale, existing 20 nearly more than 300 kinds of series of the sisal hemp product of developing mainly comprise sisal fiber, sisal hemp spun yarn, sisal hemp white palm rope, sisal hemp carpet, sisal hemp cloth, polishing wheel for sisal hemp, sisal hemp Steel cord and other sisal hemp goods etc.China produced 3.88 ten thousand tons of fibers per year in 2004, and the import sisal fiber is estimated about 3.15 ten thousand tons.Current, along with Chinese economic development, domestic sisal hemp working ability progressively enlarges, and the sisal hemp goods constantly increase, and supply falls short of demand for sisal fiber and products thereof, the selling price rising all the way, and domestic sisal hemp industry situation is very good.Yet under excellent situation, the quality management problem of China's sisal hemp fabricated product but allows of no optimist.
